What did you do to your 2015-2020 K2XX Tahoe/Yukon Today?

Good stuff!
Also impressed you were able to get the pan off without removing the exhaust.

Yeah dude it was a relief to not have to take that exhaust apart haha, I bought the gaskets just incase but it worked the way I figured it would.
I used a vacuum pump and pulled everything out but 1.5 quarts and that allowed me to tilt the pan enough to get it out.

Filled up with about half tank of E85 for first time. I had something called regular 88?? In VA once. Only 2 stations near me in NJ have E85, 1 is at the airport and they charge basically premium prices. Power Gas in East Orange has it for 3.05 today. I’ll see if she likes it through the week.

About thru half the tank and the gas mileage drop is real. Doesn’t seem cost effective with E85 and regular being so close in price. I’ll probably run a tank every now and then for the cleaning properties.

That's my experience as well.

The real value in e85 if it isn't cheaper is for almost entirely eliminating any possibility of knock. If you know you're going to beat on it, especially in the heat, then fill up with e85. Hopefully in the near future I'll add the ability to run it on my 2015 and get my tune updated.

True, there needs to be a decent price differential to compensate for the decrease in mpg if the cost is in the calculation. My usual E85 station (Maverik) just raised the price of E85 (E70, in reality) from $2.79 to $3.05, while regular 85 octane E10 is $3.14. That makes 91 octane a better deal at $3.74, with 89 octane in between those prices at $3.34.

The gap between regular 87 octane and 91/93 octane has dropped a bit as well. Used to be easily a dollar a gallon difference. I’m gonna try and use the rest of the tank for city driving and see how bad it drops there.

When I posted prices in the prior thread I was getting them from Gas Buddy. However, the idiot who posted them got the E85 price wrong; I went by the next day (not in the Tahoe) and shot a pic of the pump prices (E85 @ $2.75):



Since I drove the Hoe to the orifice today I topped up on the way home. E85 is the same price as on Monday, but everything else went 25 cents higher:



Gas prices in Colorado are bucking the national trend, which is on its way down.

Your regular unleaded is 85 octane?

Your regular unleaded is 85 octane?

That mile high life in, I'm assuming, Denver Colorado.
That elevation doesn't need as much octane.

Well when premium is only 91 octane…
